Extra copies will only be issued as a special promotion in the following cases:
- Users who own "Left 4 Dead" and then go on to purchase "Left 4 Dead + Left 4 Dead 2 Bundle" will receive an extra copy of "Left 4 Dead"
- Users who own “Half-Life 2” and go on to purchase “The Orange Box” or the "Valve Complete Pack" will receive an extra copy of “Half-Life 2”.
- Users who own “Half-Life 2: Episode One” and then go on to purchase the "Half-Life 2: Episode Pack”, “Valve Complete Pack” or “The Orange Box” will receive an extra copy of “Half-Life 2: Episode One”.
- Users who own "Dawn of War II" and then go on to purchase "Dawn of War II Gold Edition" will receive an extra copy of "Dawn of War II"
- Users who purchase the available four packs for specific Steam titles will receive three extra copies of that title to gift to friends.

Extra copies may apply as a part of some limited time promotions. In that case, information on what will be included with your purchase will be listed on the sotrefront's transaction page.
These special promotions will allow you to send a gift pass for your extra copy to a friend who does not already own the game.

Limitations
“Half-Life 2” and “Half-Life 2: Episode One” are only eligible to receive extra copies once.
For example, if you own “Half-Life 2” and/or ”Half-Life 2: Episode One” and receive extra copies for your purchase of “The Orange Box”, you will not receive additional extra copies if you then go on to purchase the “Valve Complete Pack”.

Do all duplicate purchases on Steam work this way?
No. This special offer only applies to games or game packages listed above.
